METHOD OF CRAPING FABRICS.

Specification of Letters Patent.

Patented Feb. 8, 1916.

Application filed November 19, 1914. Serial No. 873,019.

To all whom it may concern:

Be it known that I, PATRICK J. MCCARTHY, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented a new and useful Improvement in Methods of Craping Fabrics, of which the following is a specification.

This invention relates to certain new and useful improvements in methods of craping fabrics, and the primary object of the invention is to provide a method of craping fabrics in which the treatment may be continuous and expeditious, and in which the craping is produced by means ofarotating body or tumbler which acts upon the fabric in its rotation.

In the drawings the figure is a view partly in side elevation and partly in longitudinal section of an apparatus for carrying out the present invention.

A cylindrical drum or barrel 1 is provided with a series of peripheral liquid intake and discharge apertures or perforations 2, which render same foraminous. The drum is rotatably supported by means of hollow journals 3 which latter are mounted in bearings carried by standards or uprights 4 and project through the bearings. One of the journals has a driving pulley 5 mounted thereon which pulley may be driven by means of a belt 6.

Arranged within the interior of the drum and preferably extending longitudinally thereof is a series of stepped partitions 7 which provide projections that are designed to operate upon the fabric. At the inlet end of the drum is placed a vat 9 which contains boiling water or a chemical solution if desired, a suitable feed belt or other device,. indicated for example in the present case as an endless belt 10 having spurs l1, being placed within the vat to feed the material to the drum inlet. Rollers, or other guiding means, 12 are mounted on the vat and at 1 the discharge end of the'drum to engage with the fabric as clearly shown in the drawings.

In operation, the cloth or fabric is first roped or wound and enters the vat where it becomes saturated, whereupon it is introter also act to gradually feed the cloth to] the exit or discharge end of the drum, and passing out from the drum the fabric is finally dried. Any suitable reversing means,

for the belt or other driving means for the drum which may be optionally employed may be utilized It is particularly to be noted that after craping has once commenced, the operation is continuous, the drum movements belng so tlmed as to permit a proportionate amount of material'to enter the drum in relation to the amount withdrawn.

Having thus described my invention, I

claim as new and desire to secure by Letters Patent 1. The hereindescribed. method of craping fabrics, which consistsin first wetting the fabric, then in continuously operating upon an extended length of the fabric by intermittently removing portions from the wetting medium, bunching said portions in a mass in an inclosed space, then in beating up said portions while being formed lnto' and while 1n a mass by rotatmg same first 1n onedirectionand then-in another direction, and finally in removing said portions from said inclosed space.

2. The hereindescribed method of craping fabrics, which consists in first wetting the fabric, then in continuously operating upon anextended length of the fabric by intermittently removing portions from the wetting medium,bunchingsaid portions in a mass in an inclosed space, then in beating up said portions while being formed into and while in mass for a predetermined period and in simultaneously removing said portions from said space and stra ghtening out the fabric as same has been successively. beaten up at the termination of said period.'

3. The hereindescribed method of craping intermittently removing portions from the fabrics, which consists in first Wetting the name to this specification in the presence of fabric, and then in continuously operating tWo subscribing Witnesses.

Wetting medium, and bunching and beating Witnesses: up said portions in an inclosed space. ADA E. HAGERTY,

In testimony whereof I have signed my J. A. MILLER.
